Patent GB-486383-A (GB)
Title: Improvements in and relating to the extraction of wax from peat
IPC: C10G73/00
Filed: 1937-09-27
Abstract: Wax is extracted from peat by digesting with an extracting agent containing a mixture of two or more wax solvents having an approximately constant boiling point, when conditions remain constant, and thereafter separating the wax from the extracting agent, e.g. by distillation.  By returning the extracting agent, after separation of the wax, to the peat, the process may be made substantially continuous.  The peat and extracting agent are preferably digested at about atmospheric pressure and at a temperature slightly below the boiling point of the extracting agent, the digestion being continued until all the wax is extracted, which usually necessitates the extracting agent circulating through the extractor about six times.  The extracting agent may consist of (1) a binary azeotrope of minimum boiling point, e.g. a mixture of benzene and isopropyl alcohol or toluene and acetic acid; (2) a binary azeotrope of maximum boiling point, e.g. acetone and chloroform; (3) a ternary azeotrope of minimum boiling point, e.g. methyl alcohol, ethyl bromide and carbon disulphide; (4) mixtures having a constant boiling point due to their partial miscibility, e.g. trichlorethylene and ethylene glycol, carbon tetrachloride and ethylene glycol, or trichlorethylene, ethyl alcohol and water; or (5) mixtures which entrain water in the peat and the distillates of which separate into two layers either wholly or in part, e.g. benzene and ethyl alcohol or trichlorethylene and ethyl alcohol.  In the latter case the layer having the higher water content may be separated and treated to remove the water before returning to the extractor.

Title: Improvements in and relating to looms
IPC: D03D49/62
Filed: 1963-07-02
Abstract: In a travelling-wave-shedding loom, sliders which reciprocate in travelling-wave fashion to propel the shuttles also carry reed teeth to beat up the weft.  To obviate the necessity for the pitch of the teeth to be an integral fraction of the pitch of the sliders, individual sliders in recurring groups of sliders carry different numbers of teeth, so positioned that the reed as a whole has a uniform pitch.  Interchangeable sets of teeth enable the pitch to be changed to suit different fabrics.

Filed: 1955-09-14
Abstract: 792,681. Spectacle frames. AMERICAN OPTICAL CO. Sept. 14, 1955 [Jan. 17, 1955], No. 26334/55. Class 97(1) In a frame in which the underside of the upper rim portion is grooved to receive the correspondingly bevelled edge of the lens and eyewires encircle the lower peripheries of the lenses, the eyewires are resiliently extensible or connected through a spring member to the frame so that a lens can be fitted or removed without detaching or loosening their ends. A bar-like member is attached to each rim portion and can carry a detachable decorative trim. As shown, trim 38 is tubular and resiliently grips bar-like member 28. It may be made from two differently coloured semi-cylindrical pieces of material. Eyewires either enter grooves in the edges of the lenses or are grooved to fit the bevelled edges of the lenses. Bar-like member 28 of spring steel or copper-beryllium alloy has a resilient end portion 29 of reduced thickness which can be bent to relieve the tension in eyewire 32, attached to it at 33, so that the lens can be removed or inserted. The temples are carried by end pieces 24 soldered to rim portion 20. The members 28 are soldered to the rim portion 20 and provide channels 37 to receive the edges of the tubular trims 38. When in place on member 28 the trims 38 prevent portions 29 from being bent to remove the lenses. In another form the member is in the form of a flexible cable 28a extending nearly throughout its whole length and is provided with a solid end section having a shortened resilient portion 29. Rim portion 20 together with member 28 may thus be more easily bent to the curvature of a lens. The resilient extension of the eyewire may be by means of a spring loop 46 (Fig. 11) connected to the bar-like member or the whole (Fig. 12) on the end part or parts (Fig. 14. not shown), of the eyewire may be constructed as a helical spring 52 having its ends attached to the rim portion.

Title: Improvements in or relating to the removal of acetylenes from butadiene-rich streams
IPC: C07C7/10
Filed: 1960-08-02
Abstract: In the removal of acetylenes from a butadiene-bearing stream by a pretreatment (prior to butadiene extraction) with cuprous ammonium acetate solution followed by stripping acetylenes from the solution, contacting the stripped solution with an adsorbent to remove polymers and recycling the solution, the solution containing acetylenes is heated, prior to stripping, by injecting open steam.  Any dissolved butadiene may be stripped before removing acetylenes from the solution.  Stripping is effected with ammonia or natural gas, at 150 DEG F.-225 DEG F., together with steam, if desired.  The acetylenes may be stripped in two stages.  After stripping the solution is cooled to below 170 DEG F. before contacting with the adsorbent, e.g. activated charcoal.  Polymerisation of the acetylenes is unnecessary and undesirable.  Specification 743,621 is referred to.
